| 中文摘要 | Cu2O is an interesting semiconductor with extraordinary high exciton binding energy, however exhibiting weak room temperature excitonic luminescence. The issue was addressed in literature emphasizing a detrimental role of native point defects responsible for optical quenching. Resolving the problem, we propose a method to manipulate the Cu and O vacancies contents opening a gateway for optoelectronic applications of Cu2O. Specifically, applying oxygen lean conditions, we observe a remarkable suppression of V-Cu enabling strong room temperature exciton luminescence, while manipulating with V-O reveals no impact on the signal. As a result, the excitonic signature was interpreted in terms of phonon assisted transitions. (C) 2013 Optical Society of America |
